    Hello, I would like first of all to introduce myself (first post=)
    I am David, italian phisics student, always been a mac person, complete mac programming noob.

    Now about my post;
    I was trying to build something like this http://yveslebrac.blogspot.com/2008/10/cheapest-dual-trace-scope-in-galaxy.html, I could find many-a-use for it. My question is, do you think it is going to be an easy task building an application to visualize values coming out of this thing? maybe in a graph.. Do you think it is going to even be possible for my MacBook to read this scope?

    I have found some interesting pages that had me hoping it was going to be an easy task, but i really cannot understand how this works. http://developer.apple.com/mac/library/samplecode/HID_Calibrator/listing1.html

    I've also tried playing around with xcode and interface builder but i could find nothing even resembling a graph interface.

    Thank you for your time,
    David

    Creating your own graphics system and interfacing with hardware (and semi-custom hardware at that) are each fairly challenging projects in their own rights. Trying to do both, and doing so as your first project is biting off a bit too much at once.

    I would advise shelving this idea for a while and startign out with smaller projects.

    Hi

    I've not used one of those boards before but I would recommend looking at the Arduino. These boards are more powerful and you can either build them yourself or buy them ready made. The Arduino's are very easy to program using the SDK and there are lots of examples showing you how to interface the ADC channels etc.

    For the Mac side I would recommend Processing. Processing is Java based and again there are lots of examples on how to interface to the Arduino boards. The Processing API is self contained (so you won't have to learn about the Mac first) and you will be able to draw graphs etc of your data very easily.

    And finally, Arduino is an Italian project!
